These compounds possess herbicidal and pesticidal activity.

The invention relates to novel dialkyl-1-H-3-(2,4-dimethylphenyl)-pyrrolidine-2,4-diones, to processes for their preparation and to their use as pesticides (in particular as insecticides and acaricides) and as herbicides.

3-Acyl-pyrrolidine-2,4-diones have previously been described as having pharmaceutical properties (S. Suzuki et al. Chem. Pharm. Bull. 15 1120 (1967)). Furthermore, N-phenyl-pyrrolidine-2,4-diones were synthesized by R. Schmierer and H. Mildenberger (Liebigs Ann. Chem. 1985 1095). A biological activity of these compounds has not been described.

EP-A 0,262,399 discloses compounds of a similar structure (3-aryl-pyrrolidine-2,4-diones), from which, however, no herbicidal, insecticidal or acaricidal activity has been disclosed. Unsubstituted, bicyclic 3-aryl-pyrrolidine-2,4-dione derivatives (EP-A 355,599 and EP 415,211), substituted bicyclic 3-aryl-pyrrolidine-2,4-dione derivatives (EP 501,129) and substituted mono-cyclic 3-aryl-pyrrolidine-2,4-dione derivatives (EP-A 377,893, EP 442,077 and EP 497,127) are known and have a herbicidal, insecticidal or acaricidal activity.

Also known are polycyclic 3-arylpyrrolidine-2,4-dione derivatives (EP 442,073) and 1-H-3-arylpyrrolidine-dione derivatives (EP 456,063 and EP 521,334).

Novel dialkyl-1-H-3-(2,4-dimethylphenyl)-pyrrolidine-2,4-diones of the formula (I) ##STR3## have now been found, in which A represents alkyl which is optionally substituted by halogen and

B represents C₂ -C₁₀ -alkyl or

A and B together with the carbon atom to which they are bonded represent an unsubstituted cycle,

G represents hydrogen (a) or the groups ##STR4## E represents a metal ion equivalent or an ammonium ion, L and M represents oxygen and/or sulphur,

R¹ represents in each case optionally halogen-substituted alkyl, alkenyl, alkoxyalkyl, alkylthioalkyl, polyalkoxyalkyl or cycloalkyl, it being possible for the latter to be interrupted by hetero atoms, or represents optionally substituted phenyl, optionally substituted phenylalkyl, substituted hetaryl, substituted phenoxyalkyl or substituted hetaryloxyalkyl,

R² represents in each case optionally halogen-substituted alkyl, alkenyl, alkoxyalkyl, polyalkoxyalkyl or in each case optionally substituted cycloalkyl, phenyl or benzyl,

R³, R⁴ and R⁵ independently of one another represent in each case optionally halogen-substituted alkyl, alkoxy, cycloalkyloxy, alkylamino, dialkylamino, alkylthio, alkenylthio or cycloalkylthio and in each case optionally substituted phenyl, phenoxy, benzyloxy or phenylthio,

R⁶ and R⁷ independently of one another represent hydrogen, in each case optionally halogen-substituted alkyl, alkenyl, alkoxy or alkoxyalkyl, optionally substituted phenyl, optionally substituted benzyl, or together with the N-atom to which they are bound represent a cycle which is optionally interrrupted by oxygen or sulphur.

Taking into consideration the various meanings (a), (b), (c), (d), (e), (f) and (g) of group G in the general formula (I), the following main structures (Ia) to (Ig) result: ##STR5## in which A, B, E, L, M, R¹, R², R³, R⁴, R⁵, R⁶ and R⁷ have the abovementioned meanings.

Due to one or more centres of chirality, the compounds of the formula (Ia)-(Ig) are generally obtained as a mixture of stereoisomers which, if appropriate, can be separated in the customary manner. They can be used in the form of their diastereomer mixture and also as pure diastereomers or enantiomers. The following text will always mention compounds of the formula (Ia) to (Ig), for simplicity's sake, even though this is to be understood as meaning the pure compounds and also the mixtures containing various proportions of isomeric, enantiomeric and stereomeric compounds.

The active compounds according to the invention are not only active against plant, hygiene and stored product pests, but also, in the veterinary medicine sector, against animal parasites (ectoparasites and endoparasites), such as scaly ticks, Argasidae, scab mites, Trombidae, flies (stinging and sucking), parasitic fly larvae, lice, hair lice, bird lice, fleas and endoparasitic worms.

They are effective against normally sensitive and resistant types and strains and against all parasitic and non-parasitic developmental stages of the ectoparasites and endoparasites.

The active compounds according to the invention are distinguished by a powerful insecticidal and acaricidal activity.

They can be used particularly successfully for combating plant-damaging insects, such as, for example, against the larvae of the green rice leafhopper (Nephotettix cincticips), against the larvae of the mustard beetle (Pheadon cochleariae) or against the tobacco budworm (Heliothis virescens).

Moreover, they can be used in an outstanding manner for combating plant-damaging mites, such as, for example, against the greenhouse red spider mite (Tetranychus urticae) and against the fruit tree red spider mite (Panonychus ulmi).

The active compounds according to the invention can be also used as defoliants, desiccants, agents for destroying broad-leaved plants and, especially, as weed-killers. By weeds, in the broadest sense, there are to be understood all plants which grow in locations where they are undesired. Whether the substances according to the invention act as total or selective herbicides depends essentially on the amount used.

The active compounds according to the invention can be used, for example, in connection with the following plants:

Dicotyledon weeds of the genera: Sinapis, Lepidium, Galium, Stellaria, Matricaria, Anthemis, Galinsoga, Chenopodium, Urtica, Senecio, Amaranthus, Portulaca, Xanthium, Convolvulus, Ipomoea, Polygonum, Sesbania, Ambrosia, Cirsium, Carduus, Sonchus, Solanum, Rorippa, Rotala, Lindernia, Lamium, Veronica, Abutilon, Emex, Datura, Viola, Galeopsis, Papaver, Centaurea, Trifolium, Ranunculus and Taraxacum.

Dicotyledon cultures of the genera: Gossypium, Glycine, Beta, Daucus, Phaseolus, Pisum, Solanum, Linum, Ipomoea, Vicia, Nicotiana, Lycopersicon, Arachis, Brassica, Lactuca, Cucumis and Curcubita.

Monocotyledon weeds of the genera: Echinochloa, Setaria, Panicum, Digitaria, Phleum, Poa, Festuca, Eleusine, Brachiaria, Lolium, Bromus, Avena, Cyperus, Sorghum, Agropyron, Cynodon, Monochoria, Fimbristylis, Sagittaria, Eleocharis, Scirpus, Paspalum, Ischaemum, Sphenoclea, Dactyloctenium, Agrostis, Alopecurus and Apera.

Monocotyledon cultures of the genera: Oryza, Zea, Triticum, Hordeum, Avena, Secale, Sorghum, Panicum, Saccharum, Ananas, Asparagus and Allium.

However, the use of the active compounds according to the invention is in no way restricted to these genera, but also extends in the same manner to other plants.

The compounds are suitable, depending on the concentration, for the total combating of weeds, for example on industrial terrain and rail tracks, and on paths and squares with or without tree plantings. Equally, the compounds can be employed for combating weeds in perennial cultures, for example afforestations, decorative tree plantings, orchards, vineyards, citrus groves, nut orchards, banana plantations, coffee plantations, tea plantations, rubber plantations, oil palm plantations, cocoa plantations, soft fruit plantings and hopfields, in lawns, turf and pasture-land, and for the selective combating of weeds in annual cultures.

The active compounds according to the invention are highly suitable for selectively combating monocotyledon weeds in monocotyledon and dicotyledon cultures by the post-emergence method. For example, they can be employed very successfully in soya beans or winter wheat for controlling grass weeds.

The active compounds can be converted into the customary formulations, such as solutions, emulsions, wettable powders, suspensions, powders, dusting agents, pastes, soluble powders, granules, suspension-emulsion concentrates, natural and synthetic materials impregnated with active compound, and very fine capsules in polymeric substances.

These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is liquid solvents and/or solid carriers, optionally with the use of surface-active agents, that is emulsifying agents and/or dispersing agents and/or foam-forming agents.

In the case of the use of water as an extender, organic solvents can, for example, also be used as auxiliary solvents. As liquid solvents, there are suitable in the main: aromatics, such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example petroleum fractions, mineral and vegetable oils, alcohols, such as butanol or glycol as well as their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethyl sulphoxide, as well as water.

As solid carriers there are suitable:

for example ammonium salts and ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as highly disperse silica, alumina and silicates, as solid carriers for granules there are suitable: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, as well as synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks; as emulsifying and/or foam-forming agents there are suitable: for example non-ionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyclycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates as well as albumen hydrolysis products; as dispersing agents there are suitable: for example lignin-sulphite waste liquors and methylcellulose.

Adhesives such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latexes, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, as well as natural phospholipids, such as cephalins and lecithins, and synthetic phospholipids, can be used in the formulations. Further additives can be mineral and vegetable oils.

It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

The formulations in general contain between 0.1 and 95% by weight of active compound, preferably between 0.5 and 90%.

For combating weeds, the active compounds according to the invention, as such or in the form of their formulations, can also be used as mixtures with known herbicides, finished formulations or tank mixes being possible.

Suitable herbicides for the mixtures are known herbicides, such as, for example, 1-amino-6-ethylthio-3-(2,2-dimethylpropyl)-1,3,5-triazine-2,4(1H,3H)-dione (AMETHYDIONE) or N-(2-benzothiazolyl)-N,N'-dimethylurea (METABENZTHIAZURON) for combating weeds in cereals; 4-amino-3-methyl-6-phenyl-1,2,4-triazin-5(4H)-one (METAMITRON) for combating weeds in sugar beet, and 4-amino-6-(1,1- dimethylethyl)-3-methylthio-1,2,4-triazin-5(4H)-one (METRIBUZIN) for combating weeds in soya beans.

Surprisingly, some mixtures also show synergistic action.

Mixtures with other known active compounds, such as fungicides, insecticides, acaricides, nematicides, bird repellants, plant nutrients and agents which improve soil structure, are also possible.

The active compounds can be used as such, in the form of their formulations or in the use forms prepared therefrom by further dilution, such as ready-to-use solutions, suspensions, emulsions, powders, pastes and granules. They are used in the customary manner, for example by watering, spraying, atomizing or scattering.

The active compounds according to the invention can be applied either before or after emergence of the plants.

They can also be incorporated into the soil before sowing.

The amount of active compound used can vary within a substantial range. It depends essentially on the nature of the desired effect. In general, the amounts used are between 0.01 and 10 kg of active compound per hectare of soil surface, preferably between 0.05 and 5 kg per ha.

The preparation and use of the active compounds according to the invention can be seen from the following examples.

Preparation Examples Example (Ia-1) ##STR258##

67.6 g (0.223 mol) of methyl N-(2,4-dimethylphenylacetyl)-1-amino-cyclohexanecarboxylate, dissolved in 450 ml of absolute toluene, are added dropwise to a suspension of 13.38 g (0.466 mol) of sodium hydride in 220 ml of absolute toluene, at boiling heat. The batch is refluxed until starting material is no longer detectable by thin-layer chromatography. Then, ethanol is added dropwise with ice-bath cooling until the evolution of hydrogen has ceased. The solvent is evaporated in vacuo, the residue is taken up in ethanol, and the mixture is acidified with 4N hydrochloric acid at 0° C. to 20° C. The precipitate which has separated out is filtered off with suction and dried. The resulting crude product is recrystallized from chloroform/n-hexane (1:3).
